[Issue 2798] svn_load_dirs.pl: Set "svn:executable" only for newly added (executable) files.

Mark, I don't know a lot about this script, but what about the "if"
case corresponding to the "else" block that you moved the "set
executable" code snippet into -- in the following sub-conditional:

                if ($new_digest ne $del_digest)
                  {
                    print "U $source_path\n";
                    $upd_files{$source_path} = $del_info;
                  }

...wouldn't we also want to set the "svn:executable" property?
